ruby rails activerecord Ruby

I'm trying to figure out I'm having trouble with I've spent hours debugging this and I'm relatively new to this, so bear with me... I'm working with an scenario with ActiveRecord callbacks in my Rails 7 application. I have a model `User` where I want to send a welcome email after a new user is created. I'm using the `after_create` callback, but it seems to be causing unexpected behavior. Specifically, when I create a user, I'm seeing duplicate emails being sent, and I'm not sure why. Here's a simplified version of my `User` model: ```ruby class User < ApplicationRecord after_create :send_welcome_email private def send_welcome_email UserMailer.welcome_email(self).deliver_later end end ``` When I test this in the Rails console with: ```ruby User.create(email: 'test@example.com') ``` I receive two emails instead of one. I've checked the logs, and it shows that the `send_welcome_email` method is being called twice. I'm not using any nested attributes or associations that could be triggering this callback multiple times. I've also ensured that there are no previous records with the same email that might be causing the callback to fire again. I tried debugging using `byebug`, and I see that the callback is indeed hit twice, but I need to figure out why. To isolate the scenario, I created a new Rails 7 app and implemented the same callback, but it worked as expected there. I'm suspecting it might be something in the configuration or other callbacks in my application. I've checked other models, and they don't have similar issues. Has anyone experienced this before, or does anyone have suggestions on what could be causing this behavior? Any help would be greatly appreciated! How would you solve this? This is for a mobile app running on Ubuntu 22.04. I appreciate any insights! This is part of a larger application I'm building.
